    • Locate those 2 tabs on the left side inside the device.

    • Lift them up off the metal brace

    • You may have to bend the metal support bar to remove the case. Bend it back if you do.

    This step could really use a better illustration of the removal technique. The plastic here is extremely stiff and it can be hard to bend it enough to move the tabs.

    This is the best technique I found, that will avoid damaging the plastic facing of the case. I am using the iFixit photo as a guide. Take a flathead screwdriver and place it down within the DS412, head facing up. Stick the head in between the metal bar and the plastic casing, and at the midpoint between the two tabs. Apply gentle pressure.

    I played around with a flathead screwdriver at first but it scratched the metal and I was worried it might damage the plastic casing.

    So I found the least destructive way to remove the plastic casing from the metal cage is, by pushing with all four fingers up against the black plastic inside the housing (so behind the metal bar) while your thumb holds on against the outside of the housing and simultaneously pushes the whole housing to shove the two black plastic tabs over the metal bar.

    Please note, the tabs are just to block the outer case from sliding back in the next step — there’s no big trick or force required here, just flex the side of the case enough to get the tabs to slide past the metal bar.

    Rob Miller - Responder

    You probably won’t like my solution to this nerve-wracking stage, but simply use a Stanley knife to slice the top of the tabs at an angle and the case can then be slid back relatively easily over the metal bar. It’s my NAS and the screws on the back will hold the case close perfectly well without needing those tabs locking as rigidly as they did before I attacked them. :-)

    It’s a daft easy-assembly, difficult-disassembly case.

    Richard Lewis - Responder

    Coming back to this comment on reassembly: Actually the tabs click back into place very nicely and hold the case in place, just not quite as firmly as before. But still will require a bit of force to remove the cover again. So perfect!

    Richard Lewis - Responder

    I used 2 plastic (!) tire lifters from the bicycle tool box. They fit under the hooks perfectly and I could easily move back the housing and made no damage whatsoever.

    Chrisitan Kolb - Responder

    I did as Richard Lewis:

    Slicing the tabs makes for much easier assembly and disassembly.

    And that was very helpful later

    • Remove the screw securing the I/O board.

    I made the mistake of placing the I/O board behind the frame when I reassembled. I quickly found out my mistake. This photo was helpful.

    • Pull these tabs and remove the ram

    • Old and new Ram

    • The old RAM's part number is: M3SN-1GSFCCM7-GA14

    • To reassemble your device, follow these instructions in reverse order.

    I used a CMSO4GX3M1A1333C9 DDR3 4GB PC-1333 CL9 CORSAIR Value Select module.

    That worked nicely in my setup.

    I had to refit it after the system did not boot correctly, so it was nice to be able to get the cover on/off without the tabs on the side.

    I found that it was easier to test the DDR module by just assembling the mainboard, ioboard and the backplane (without the screws, the cover and without any disks in the bays).

    When powering on the NAS the blue power LED blinks for 3-4 minutes and then the orange status LED starts blinking as there are no disks in the bays, but the good thing is that when you see the blinking orange LED you know that the DDR is actually working.

    If your NAS just continues blinking the blue power LED "forever", the DDR module is either not working or you need to refit it in the slot.

Hi is it also possible with a Synology ds216play? Or is the RAM not modular in this Drives?

markusguenther30684 - Responder

Very nice guide. Thank you!

mbs - Responder

Thank you for the guide, just to ease it up a bit for everybody following, the best way to pull the two tabs from step 4 was to use small spoon (or anything metal) and use it as a crowbar from the inside (do not try to put force from the outer rim, but really from inside of the Synology itself (against the metal beam the tabs are holding to).

Ondrej Palat - Responder

Thank you very much.

Olivier Claude - Responder

did these steps and now my DS412+ won't boot anymore. just the blue power light for a few seconds, no hard drive or fan will turn on.

after putting the old RAM in the slot nothing changed. cannot find any error, how do I find out what's wrong here???

Andreas Hanny - Responder

Super facile, en 10 minutes même pas c'est fait !!

This guide was great. Thanks for posting it!

I upgrade to 2gb RAM last night with no problems. I used "Kingston Technology ValueRAM 2GB 1333MHz DDR3 Non-ECC CL9 SODIMM SR X16 Notebook and Portable Memory KVR13S9S6/2" from Amazon.

System is humming along nicely now.

Jeff Smith - Responder

Thank you for this guide.

I upgrade my RAM without any trouble.

The use of two tea spoon to lift the tab in step 4 is very useful.

Marc Jean - Responder

May God bless you for this amazingly clear and detailed tutorial! I was able to install a 4GB module sooooo easily and now my 412+ after more than 5 years of activity is reborn into a new life!!! Thank you so much!

casagni - Responder

Thank you very much for that excellent description.

With it I was able to fix my dead DS412+ with changing the onboard battery ;-)

Oliver Geissler - Responder

With the help of this guide and Youtube watch?v=eHCf51AytLM I was able to replace the onboard CR2032 battery in my DS413. Thank you.

I am still getting the dreaded flashing blue power switch light though, which is a different problem.

Without any HDD attached, the power light stays on, and the status light flashes.

Worked like a charm! Thank you very much.

nerfologist - Responder

remember to buy low voltage RAM. this is a must

Cyrus Leung - Responder

What do you mean with low voltage RAM Cyrus: 1,35V and not 1,5V?

Can I Use DDR4 or DDR3L So-Dimms or is a pure DDR3-module absolute necessary?

I prefer Kingston or Corsair and 8GB or maybe 4GB and ECC instead of non-ECC.

Here’s a Corsair module that caught my attention: CMSO8GX3M1C1600C11 from Amazon.

Is this a good choice?

Thank you!

Mark -

8 years and the 412+ is still going strong on the original 4TB WD Red drives. 4x the ram will breathe new life and hopefully, get me many more years to come. It’s at least 2x faster with more ram. Just using this guide to clean out years of dust is probably worth it, even if you are upgrading the ram :)

Chris Kirby - Responder

synology ds412+ after upgrade RAM lose all data??

tanzibul hasan tazin - Responder

Excellent guide, works also for the DS 415+. Thanks
